结直肠癌是世界上最常见和最致命的癌症之一。结直肠癌的一个重要致病因素是溃疡性结肠炎。在这项研究中,我们研究了胡椒长明(PL)对葡聚糖硫酸钠(DSS)诱导的急性结肠炎和氧化偶氮甲烷(AOM)/DSS诱导的结直肠癌小鼠模型的治疗作用。我们的结果表明,PL可以通过下调促炎细胞因子环氧合酶-2和白介素-6以及上皮间质转化相关因子、β-连环蛋白和snail的表达来抑制DSS诱导的小鼠结肠炎的炎症并减少AOM/DSS诱导的小鼠结直肠癌的大肿瘤(直径> 2 mm)的数量,但未能改善结肠炎症状并降低结肠肿瘤的发生率和数量小肿瘤(直径 <2 毫米)。这些数据表明 PL 可能是治疗结肠炎和结直肠癌的有效药物。
Colorectal cancer is one of the most common and lethal cancers in the world. An important causative factor of colorectal cancer is ulcerative colitis. In this study, we investigated the therapeutic effects of piperlongumine (PL) on the dextran sulfate sodium (DSS)-induced acute colitis and azoxymethane (AOM)/DSS-induced colorectal cancer mouse models. Our results showed that PL could inhibit the inflammation of DSS-induced mouse colitis and reduce the number of large neoplasms (diameter >2 mm) of AOM/DSS-induced mouse colorectal cancer by downregulation of proinflammatory cytokines cyclooxygenase-2 and interleukin-6 and epithelial-mesenchymal transition-related factors, β-catenin, and snail expressions, but fail to improve the colitis symptoms and to decrease the incidence of colonic neoplasms and the number of small neoplasms (diameter <2 mm). These data suggested that PL might be an effective agent in treating colitis and colorectal cancer.
